The 24.18 ct. Cullinan Dream, an intense blue colored diamond sold for $25.4 million at Christie’s June 9 auction in New York.

It is flanked on either side by a tapered baguette-cut diamond and set in a platinum ring, inscribed “Cullinan Dream”.

The diamond was cut from a 122.50 ct rough diamond that was discovered by Petra Diamonds in 2014. It was named after the mine where it was discovered, The Cullinan Mine in Southern Africa.

The mine is best known for the discovery of the world’s largest rough diamond ever found at 3,106 carats. The finished diamonds cut from that rough are now part of the British Crown Jewels.

The Cullinan Dream is a cut-cornered rectangular mixed cut diamond and is of the Type IIb variety as classified by The Gemological Institute of America.

“Type IIb gems contain a small amount of the element boron that was trapped in the crystal carbon structure during their formation that can give rise to a blue or grey coloration,” Petra Diamonds said in a statement.
